These days, I keep getting eczema..

Maybe because it's hot and just humid..

A small eczema-like rash is appearing on my footㅠㅠ

I thought it would get better if I washed and dried it well at first...

It seems to be getting bigger and wider as it happens..

I'm a bit hesitant to go to the hospital because of this... Please recommend any methods or medications that can cure eczema.

I want to solve it on my own alone, so I'm shyㅋㅋㅋ
